Ivanhoe’s 2026 Kakula copper dip and 2027 ramp-up: planning notes for mine engineers

30 Second Briefing
Ivanhoe Mines expects contained copper output at the Kamoa-Kakula complex in the DRC to fall to 380,000–420,000 tonnes in 2026, down from 437,061 tonnes of copper concentrate in 2024, before rising about 30% to 500,000–540,000 tonnes in 2027 at grades of 3.5–4.5%. Seismic-induced flooding in May halted underground mining for about three weeks, with dewatering now 70% complete in the western zone and 60% in the eastern zone, and 13.4 km of workings rehabilitated, including 4.6 km dewatered. A revised life-of-mine plan due late Q1 will assess lifting mining rates to 17 Mt/y, up from about 6 Mt of ore expected in 2026, and a potential new concentrator.
Technical Brief
- Dewatering completion is asymmetric: 70% in the western zone versus only 60% in the eastern zone.
- Rehabilitation has covered 13.4 km of underground workings, including 4.6 km already dewatered and re‑entered.
- Analysts flag that investors are tracking dewatering percentages more closely than tonnage guidance, effectively treating water control as a leading safety indicator.
- For other deep, high‑grade underground operations, the case underlines the need for robust seismic monitoring and rapid‑deployment dewatering capacity in life‑of‑mine planning.
Our Take
With Kakula copper grades guided at roughly 3.5–4.5% and a potential mining rate under review of up to 17 Mt/y, the Kamoa-Kakula complex in Congo remains positioned as a very low-cost, high-grade supplier in a copper market where other majors like BHP are pursuing growth mainly through large-scale M&A, as seen in its recent approach for Anglo American.
The three-week shutdown and ongoing dewatering/rehabilitation at Kakula (13.4 km rehabilitated, 4.6 km dewatered so far) underline how seismic and hydrogeological risk is becoming a recurring operational theme in our safety-tagged copper coverage, which can tighten near-term supply even at otherwise well-capitalised assets.
Given that the Democratic Republic of Congo accounts for about 70% of global cobalt mine production in the referenced data, any sustained disruption or mine-plan change at Kamoa-Kakula could have knock-on implications for cobalt by-product availability alongside copper, particularly for battery supply chains tracked in our critical-minerals pieces.
